说明：  用VC__NET编写鼠标交互式绘图程序 主要介绍了在面向对象的VC++.NET语言环境下,通过使用WM_LBUTTONDOWN, WM_MOUSEMOVE, WM_LBUTTONUP等鼠标事件消息,采用橡皮条绘图法,编写一个鼠标交互式绘图程序.该程序可实现绘制随机的平面图形,也可通过鼠标的拖动画出大小不同的圆,椭圆,矩形,直线等平面图形.
(VC__NET the preparation of the mouse using an interactive drawing program primarily in the introduction of object-oriented VC++. NET language environment, through the use of WM_LBUTTONDOWN, WM_MOUSEMOVE, WM_LBUTTONUP news events such as the mouse, using rubber graphics article method, the preparation of a mouse Interactive graphics procedures. The program can realize the planar random drawing graphics, the mouse can also be of different sizes and drag to draw a round, oval, rectangle, straight line, such as planar graph.)
